Mechanism of action
The components of the drug, ethinyl estradiol and norgestimate, inhibit the secretion of the gonadotropic hormones of the pituitary gland, control the process of maturation of the egg, prepare the uterine mucosa for implantation of a fertilized egg. As a result, the process of ovulation is inhibited and the egg does not mature. Also, Tri-Estarylla changes the properties of the cervical canal, therefore, the permeability of this genital tract for spermatozoa is reduced, and the inner uterine membrane is also affected.

Interactions
Drugs that induce estrogen metabolizing enzymes reduce the contraceptive effectiveness of Tri-Estarylla. The induction of these same isoenzymes can lead to a decrease in the blood concentration of norgestimate in the contraceptive. In this regard, you need to take with caution the following drugs: St. John’s wort, barbiturates, carbamazepine, phenytoin, sulfonamides, pyrazolone derivatives, rifampicin
Some protease inhibitors and some antiretroviral drugs (indinavir, ritonavir) can increase or decrease the concentration of ethinyl estradiol and norgestimate in the blood.
Some antibiotics (ampicillin or tetracycline) can violate the intrahepatic circulation of estrogen, which results in accelerated elimination and decreases the concentration of ethinyl estradiol.
Pregnancy and breastfeeding
The drug is contraindicated for use during pregnancy and lactation.

Precautions
After cessation of hormonal contraception, the function of the female genital glands is quickly restored, which ensures a normal ability to conceive.
Use of Tri-Estarylla after childbirth or abortion (miscarriage) is recommended after the first normal period.
Smoking women who take COCs have an increased risk of developing vascular diseases with serious consequences (myocardial infarction, stroke). The risk increases with age and with the number of cigarettes smoked per day (especially in women over 35).
Before taking birth control pills and every 6 months, you are recommended to undergo general medical and gynecological examinations (examination of the mammary glands, liver function, blood pressure and cholesterol concentration in the blood, urinalysis).
The efficiency of the contraceptive decreases with regular use of ethanol.
Diarrhea and vomiting can reduce the contraceptive effect of the drug. If you have these gastrointestinal disorders, you should keep on taking the pills at your usual time and use additional non-hormonal methods of birth control).
Moderate bleeding during the course does not require discontinuation of the medication. If severe bleeding occurs, stop taking the tablets and consult a gynecologist.
Stop taking pills immediately in the following cases: unusual migraines/headaches, early signs of phlebitis or phlebothrombosis, jaundice, visual disturbances, cerebrovascular disorders stabbing pain of obscure etiology when breathing or coughing, pain and tightness in the chest, an increase in blood pressure, 3 months before the planned conception and 6 weeks before the planned surgical operation followed by prolonged immobilization.
